IMPROVEMENT IN COTTON-PRESSES.

specification forming part of Letters Patent No. 119,367, datedSeptember 26, 1871.

To all 'whom it may concem:

Be it known that I, J Acon B. KNIGH'r, of New Orleans, in the parish ofOrleans and State of Louisiana, have invented a new and usefulImprovement in Ootton-Presses; and I do declare that the following is atrue and accurate description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon, andbeing part of this specification, in which- Figure 1 is a perspectiveview of the improved sectional metallic-framed cotton-press with theplaten shut down, and the looped iron bars connecting the bed and theplaten passed over the shoes on the end of the trussed bar on theplaten. Fig. 2 is a detached view of the platen. Fig.-3 is a perspectiveview of the head or top of the press, withthe looped iron bars detachedfrom the shoes on the platen and the platen turned back so as to leavethe whole press open for greater convenience in filling the same withcotton.

In the accompanying drawing like letters des-V ignate like parts.

The nature of this nvention relates to improvements in the constructionof a cotton-press, whereby the press is greatly strengthened, is madeless cunibersome and more easily operated, the press being more easilyfilled with cotton, and the bale more readily removed when pressed. Theinvention consists: First, in the construction and arrangement ofstraining-rods of iron and iron trusses, in combination with the bed andplaten. Second, in the peculiar construction and arran gement of thevarious parts, as more fully hereinafter described.

In the accompanying drawing, A is the body of the press and B is thehead, into which the cotton is thrown loose through the openings in thehead or top thereof. G is a platen, provided with journals a upon theends of the cross-timbers b, said journals being designated to engage'With the loops c, which in turn are secured to the top of the framewhich supports the press in such a manner that the platen may be openedand turned back at pleasure. The center crossbar D, which is designed tostiffen and strengthen the platen, is in its turn further stiffened andprevented from springing under pressure by the iron truss E,the outerends of which pass through and are secured by proper'nuts to themetallic shoes F, which are secured upon the ends of the said bar D. Theupper faces of these shoes are semicircular in `form, and are providedwith grooves d. The bed G is stiffened by the truss K, and in the bed isinserted the nut L, which is provided with sockets I, into which thelevers J are inserted for the purpose of giving a rotary motion to thenut, thereby elevating or lowering` the screw H, to the top of which thefollower (not shown) is attached. The ends of the truss Kv 'pass throughthe metallic. shoes M, which are secured at each end of the timbersforming the bed G. N is a double straining-rod, the upper end of whichis looped, as shown, while the lower ends pass vertically through theshoes M and are secured by suitable nuts.

When it is desired to fill the press the follower is run down to or nearthe bottom of the body, the looped ends of the straining-rod N aredisengaged from the groove d. in the shoes E of the platen, which isthen thrown back, as in Fig. 3, leaving the mouth open for greaterfacility in filling the press.. After the press is filled the platen isclosed down, as shown in Eig. 1, and the loops of the straining-bars areengaged with the before-named grooves d. The follower is then driven upby ineansof the nut and screw, and the cotton is compressed into thehead of the press, when it is baled and secured in the usual way.

Whatl claim, and desire to secure by Letters Patent, is-

1. The combination of the trusses E and K, the straining-rods N, theplaten O, and the bed G, all constructed, arranged, and Operatingsubstantially as and for the purposes set forth.

2. In the cotton-press herein described and shown, the arrangement ofthe body A, head B, platen O provided with the truss E and shoes F, thebed G provided with the truss K and shoes M, the straining-rods N, nutL, screW H, levers J, and the follower, all constructed and operatingsubstantially as described and shown.
